comparison
Virtualization Manager can retain historical data for performance, state, event, and
configuration data, and can visualize this data in a manner that helps you
understand the life cycle of virtual machines and hosts. Select one or two virtual
machines or hosts from a search query result list on the search results page, and
then click Compare for further historical analysis.
Using DNA comparison
DNA™ Comparison consists of two parts that together comprise the unique
attributes of a virtual machine or host throughout its life cycle.
The first part is the identity attributes. These make up the combination of
unchanging attributes that define what uniquely identifies a virtual machine or a
host through typical life cycle transitions.
The second component of DNA™ Comparison comprises all the remaining
attributes of virtual machines or hosts that are subject to change and that uniquely
identify it at a particular point in its life cycle. This second class of attributes is
available for historical analysis by the Compare feature.
The first step to performing comparisons is to find the VMs or hosts. Select the
objects you want on the search results page, and then click Compare.
The following screen is displayed to compare the two objects. This is an overview
of the comparison of every attribute collected for the objects at the time of the most
recent data collection interval.
